“…This also indicates that farms that received extension visits are more technically efficient than farms that did not get any advisory service. This result is also consistent with the findings of Beyan and Endrias (2013) and Oduntan et al (2016). Land ownership had a negative relationship with technical inefficiency.…”

The ability of Nigerian agriculture to perform its role in the development of the economy has been on the decline in the last three decades. Therefore, the 2030 Agenda's historic commitment to rid the world of the twin scourges of poverty and hunger cannot become a reality if nothing is done about improving resource productivity so as to reduce poverty. This article examined the effect of resource productivity of maize-based farmers on poverty reduction in South-West, Nigeria. Multi-stage sampling procedure was used to select 180 respondents and data were collected with the aid of a structured questionnaire. The stochastic frontier production function, poverty index and probit regression model were used to analyze data from the study. Results showed that age, farming experience, cooperative membership, credit, extension visits, farm distance, and land ownership were significant determinants of efficiency of maize-based farmers. The poverty incidence, poverty gap and poverty severity were 42%, 50% and 11.2% respectively. Results further showed that efficiency and other variables were significant determinants of poverty among respondents in the study area. Policies that facilitate increased production of maize, increased level of education, increased cooperative membership, and access to credit are essential to help reducing poverty among maize-based farmers and among the rural poor in general.

“…The results also show that a percentage increase in each of the inputs would increase maize output by 4.64 percent. Oduntan et al (2016) observed decreasing return to scale among maize-cowpea farmers in South West Nigeria while Bwala et al (2015) observed returns to scale of 1.06 in North Central Nigeria in a production frontier that did not control for environmental factors. Table 3 also presents partial elasticities of substitution for the conventional input pairs.…”

This paper uses a translog stochastic frontier model to estimate the relationship between maize yield and an interplay of soil carbon, soil nitrogen and inorganic nitrogen fertilizer using plot-level data collected from smallholder farmers in Dedza and Ntcheu Districts of Malawi in 2013/2014 growing season. One of the covariates in the model is nitrogen applied to a plot from inorganic fertilizers. Farmer use of nitrogen is influenced through participation in a non-random targeted Farm Inputs Subsidy Program (FISP) of the Malawi Government. A control function approach is therefore applied to correct for possible endogeneity of participation in the FISP.Results show that inorganic nitrogen fertilizer has significant positive effect on maize output whereas an increase in soil carbon is associated with low maize output but interaction between soil carbon and soil nitrogen as well as with inorganic nitrogen significantly increases maize output. These results seem to be linked to Carbon to Nitrogen (C:N) ratio in the soil. The accumulation of C beyond the optimal C:N ratio is known to reduce rate of decomposition, nutrient cycling, shoot: root ratio and biomass in grasses including maize. Under such circumstances, increasing nitrogen brings the C:N ratio to beneficial levels. The results further show that inorganic nitrogen is a substitute to labour, seed and land. The substitution relationship suggests that improvements in inorganic nitrogen require reduction in labour, seed use and land. It has further been shown that only 45.03% of the plots have marginal value cost ratios of greater than one which shows that considerable number of plots are not profitable. For 66.20% of the plots, applied inorganic nitrogen fertilizer exceeds optimal levels signifying suboptimal use of the input. The results suggest that inorganic nitrogen is profitable at low levels of application which is largely due to prevailing high nitrogen-maize price ratio. The prominent issue for policy consideration from these results is that soils in Malawi are depleted of nitrogen leading to unfavorably high C:N ratios which negatively impact maize production. Given that nitrogen-maize price ratio is already high in Malawi, farmers will need programs that enhance their access to nitrogen fertilizers at low prices for nitrogen fertilizer application to be profitable. Such programs need to be implemented simultaneously with a package of intensification practices that fix and retain nitrogen in the soil.
